🌞#SARFact day⁉️ DYK #Harmony mission was selected as the 10th & new @ESA_EO mission with two identical satellites orbiting Earth in convoy with #Sentinel1. Each #Harmony satellite will carry a receive-only #SAR & a multiview thermal-infrared instrument. #TheMoreYouKnow #EOChat
🌞#SARFact Monday! ⁉️DYK coherent targets' backscatter is generally fully polarized & these usually are man made structure such as buildings? 🏨🏫🏢 #SAR #TheMoreYouKnow #EOChat
🌞#SARFact day!! #DYK⁉️#SAR systems can have different polarisation configurations? #Singlepol transmits & receives a single polarisation, mostly the same direction, resulting in a HH or VV imager (first designation is the transmit & the second is receive direction) /1

Congrats, @SistersOfSAR! You've accomplished more in 2 years than many do in a lifetime! 🤩🎉
You are making #SAR accessible on #SARFact & #PictureDay, growing capacity on #TrainingTuesdays, increasing visibility of #SAR_STARS & #DiversityDay!
We celebrate YOU! #GoldenAgeOfSAR
🎇It's our 2nd #Twitterversary today! 😍Thank you to everyone who's been on the ride since 2020 & those who have joined us along the way! 🙏Many thanks to our collaborators & all of our ⭐️#SAR_STARS! We can't wait for Year 3! 🥳Cheers from @LDR1, @Go__pika & @SAR_ahBanks
🌞Happy #SARFact Day⁉️Orbit positioning control for #SAR satellites are defined using an orbital Earth fixed "tube". Multiple #SAR satellites within the same orbit such as #RCMSatellites, #TerraSARX & #PAZ can allow for reduced revisit times for #InSAR

🌞Happy Monday! #SARFact Day! ⁉️Have you heard about @predasar, a new #SAR small #satellite data provider & launching the first of their #SAR constellation on @SpaceX in late 2022! ➡️Check out https://t.co/HReNnb1BF9 to learn more! #EOChat #GoldenAgeofSAR #TheMoreYouKnow
🌞Happy Monday #SARFact Day! ⁉️DYK Complex number implies that the representation of a signal includes both magnitude & phase values? 〰️〰️🛰️ https://t.co/cZdcyIsqge #TheMoreYouKnow #EOCchat
🌞#SARFact Monday! #DYK⁉️ #SAR data can be calibrated, without the need for atmospheric correction, leading to consistent #timeseries.
#TheMoreYouKnow #SARisAwesome!
🌞Happy Monday! #SARFact day⁉️ DYK #SAR is generally side-looking with the near nadir track called near range & farthest from the nadir called far range, unlike #optical sensors which are usually nadir looking. #KeydifferencesSAR_Optical #TheMoreYouknow #EOChat
🌞Happy #SARFact day⁉️ DYK #SAR is an active sensor transmitting microwave radiation & receiving the portion scattered back while optical sensors are passive & sense reflected radiation in parts of the visible & infrared spectrum #EOChat #TheMoreYouKnow #KeyDifferencesSAR_Optical
🌞Happy Monday! #SARFact Day! ⁉️ "How does the polarization of a scattered EM wave differ between the forward scatter alignment (FSA) & the Backscatter alignment (BSA)?" Check out ➡️https://t.co/QA1Kwmu3TD for the answer & other #SAR trainings!🛰️〰️#SAR #TheMoreYouKnow #EOChat
🎓#TrainingTuesdays! If you read yesterday's #SARfact & want to learn more about #PolSAR (SAR polarimetry), have a look at this Polarimetric Workstation: 👉https://t.co/PsorxOUdZe
(2/2) 🌞#SARFact Monday! Cross-pol (VH or HV) images can help discriminate between land/water/ice due to the minimal backscatter from water in these bands & stronger🦾 backscatter from land (& ice, to some degree) due to volume scattering. #DYK⁉️
